Sand is mainly composed of divided rock and mineral particles. Depending on the local environment and rock resources, the composition of sand can vary in many different ways. However, in general, silica and calcium carbonate are the most common constituents of sand. Sand can be categorized in terms of particle size. In most cases, sand particles range in diameter from 0.063 mm to 2 mm. According the standards stipulated by International Organization for Standardization (ISO), sands are graded in three levels (fine, medium and coarse) by their ranges.
Sand is frequently used in the construction industry. Brick is made of sand, clay and other materials while concrete and glass is mainly composed of common sand. Moreover, playing with sand is fun. Sand has been used in children’s play and in the making of sand castles for many years. In recent decades, some city administrators even decide to create or improve local beaches by moving more sand to the original coastal areas. Also marked by outstanding drainage characteristics, sandy soils are ideal for planting watermelons and peanuts, etc. In addition, aragonite sand is needed in aquaria for saltwater reef tanks.
However, the production of quality sand requires advanced sand processing technology and professional operators. Cutting-edge equipment and standard process control are the key to manufacturing sand of high-quality. With portable sand making plants, sand manufacturers can complete the sand processing on wheels easily and efficiently. Portable plants are not only well adapted to crushing and screening processes with demanding requirements but also function smoothly as one part of a multiple-step process.
To be more specific, portable sand making plants are generally equipped with almost anything that is needed in the sand manufacturing process: vibrating feeder, cone crusher, sand making machine, vibrating screen, sand washing machine, etc. Because of the king pin arrangement of the portable plants, the final product can be collected and transported to customers in less time. Moreover, the construction of portable sand making plants is relatively easy and cost-effective with high availability.
Portable sand making plants can be either constructed as a two-stage system or a three-stage one with for sand screening and sand washing. The separate parts of plants can also work independently. For sand manufacturers, portable sand making plants are beneficial in many ways. First of all, portable plants greatly reduce the production costs because the expense on the maintenance of quarry can be completely spared and the waste materials can be separated on the spot. Moreover, it helps improve workplace safety since equipment like sand washers and sand makers are arranged nearby. In addition, the possible negative effects on the environment around the plant can be reduced to the least. And operators of cone crusher and sand screen can coordinate well with each other while controlling different types of operations so as to achieve the results required by consumers and improve efficiency.
